SEALING CUSHIONS

Benefits

Designed for temporary pipe closure
Sealing cushions are used to temporarily close pipe sections during maintenance, testing, or short term works. They provide a lightweight, practical sealing option where conventional plugs may be harder to use due to size, weight, access, or pipe shape.

No additional bracing required
In suitable applications, sealing cushions do not require additional bracing. This helps simplify setup, especially in manholes, chambers, and confined areas where space and access are limited.

Lightweight and compact for tight access
Sealing cushions are compact and easier to handle in tight spaces. They can be inserted through standard or narrow manholes and take up less room during transport and storage.

Suitable for different pipe shapes
With the correct configuration, sealing cushions can be used in non circular pipes, including ovoid, kite shaped, mouth, rectangular, square, and egg shaped sections. This makes them useful where standard pipe plugs may not seal effectively.

Repairable and reusable design
Sealing cushions are designed to be repairable and reusable, helping reduce replacement costs over time. Their durable construction supports regular use when selected for the correct pressure and application requirements.

Wide diameter coverage
One device for many diameters – 150mm – 3600mm. Individual cushions can cover multiple diameter ranges, helping reduce the need to carry separate stoppers for every pipe size.

Before selecting a cushion, crews should check diameter range, working pressure, back pressure, installation length, air volume, weight, and any special sealing or by-pass requirements.

Description

Sewer sealing cushions for temporary pipe closures and pressure testing across New Zealand. These German-made cushions are designed as a lightweight and compact alternative to conventional pipe plugs, especially where access is tight or the pipe profile is less standard. They are established as the safest and most economical pneumatic pipe stoppers available.

Sealing cushions are suited to underground pipe work where crews need a practical way to close off a pipe without relying on heavy or bulky equipment. Their compact design allows them to be inserted through standard or narrow manholes and handled more easily in confined spaces.

Unlike conventional inflatable plugs, these cushions do not expand by material stretching. They are designed to provide a secure seal without the need for additional bracing in suitable applications, helping reduce setup requirements where space and access are limited.

The range includes options across a wide spread of pipe diameters, with selected configurations available for non circular cross sections, leakage testing, and by-pass requirements. Before choosing a cushion, it is important to confirm the pipe size, shape, pressure requirements, access, and whether special sealing or by-pass functionality is needed.
